i've been following this very closely all over the country and in my hometown of baltimore, which has charter schools but in baltimore's charter schools, the teachers are unioned and the parents have a lot of stay. they are not owned by private companies. nonprofit groups are helping to manage the schools. it is a very different situation. i think what's happening on this teach the test, rahm emanuel puts his kids in the lab school. a great school. the head of the lab school said at the beginning of the strike, believe in testing. i don't believe in these kind of tests for our children. his own kids don't have to work for that. >> this is the point. i've been at elite, you taught at elite universities, princeton and others, that have gone away from using s.a.t.s for their entrance requirements. this he recognize that the main thing that standardized tests tell us is about the educational and economic situation of the family. if your family has some wealth, if your family has college educated people, you do well on standardized tests and they have very little to do with what's going on
